feat(content): comprehensive extraction hardening, code mode UI, overnight plan

- Relax isBookLikeResponse threshold (>=2 to >=1) - Widen book patterns: inline prose, verb-preceded, numbered bold, em-dash - Remove overly aggressive film/song gating on book extraction - Allow songs to coexist with film/book tags (explicit tags always returned) - Strengthen TV patterns: seasons, created by, standalone "tv" query match - Fix TV_EXT_RE to handle both Title|Year|Creator and Title|Creator|Year - Widen place patterns: type word search in descriptions, bold fallback - Add "pizza" to isPlaceQuery and preferredFirstTab - Add Code tab: isCodeQuery, isCodeLikeResponse, extractCodeBlocks, wiring - Fix image threshold: single image with meaningful alt text shown - Refactor filterTabsByContext: specialized paths now append remaining content - Add code mode UI: orange input styling, design system selection, file selection - DesignSystemGrid: selection toggle only on checkmark, card click opens detail - Add 64-test extraction quality test suite - Update overnight plan.md and prompt.md for hardening run Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
